WARREN r. FRASER, OF

DORCHESTER, MASSACHUSETTS.

DEVICE FOR FEEDING LACING-HObKS AND THE LIKE.

T on whom it may concern:

Be it known that I, \VARREN F. FRASER, a subject of King Edward VII,residing at Dorchester, in the county of Suffolk and State ofMassachusetts, have invented new and useful Improvements in Devices forFeeding Laeing-liooks and the Like, of

which the following is a specification.

This invention relates to a device for sepfo arating lacing-hooks or thelike from a mass of the same contained in a ho mm and. feeding the sameto a raceway leading out of said hopper to any desired point in amachine whcre'they may be driven and clenched in 1 5 sheet material.

The object of the invention is to provide a device of the character setforth which will separate a large number of lacing-hooks per minute fromthe mass of lacing-hooks con- 0 tained in the ho )por andfeed them tothe raceway, the mechanism b which the lacinghooks are taken from thehopper and fed to the raceway being capable of continuous rotation andthe raceway so constructed and 5 arranged with relation to thepicker-blade,

by which the lacing-hooks are taken from the hopper and carried to theraceway, that hooks can feedonto the raceway from the picker-blade whilethe picker-blade is rotating.

The invention consists in the combination and arrangement of parts setforth in the fol lowing specification and particularly pointed out inthe claims thereof.

Referring to the drawings, Figure 1 is a side elevation of my improveddevice for feeding lacing-hooks. Fig. 2 is a central longitudinalvertical section, partly in elevation, of the same. Fig. 3 is anenlarged detail section, part1 in elevation, taken on line 3 3 of Fig. 1100 ing toward the left in said figure,

illustrating the position of a laeing hook on the raceway. Fig. 4 is asection of the hop per, with the raceway and bottom of the hopper shownin plan, the sectional portion being taken on line 4 4 of Fig. 2. Fig. 5is an enlarged section, partly in elevation, taken on line 5 5 of Fig. 4looking in the direction'of the arrow in said Fig. 4 and illustrating aporvtion of one of the picker-blades with lacinghooks thereon which arein position to slide dqwnwa'rdly therefrom upon the raceway t e hopperbeing shown broken away in said v ts w tosave space in the drawings.Fig. 6 is als tr ting one of the picker-blades moved for Specificationof Letters Patent.

Fig. 7 is another illustrative viewsimilar to Figs. 5 and 6, illustrating the raceway filled withlacing-hooks and the end of one of the pickerblades passing over thatportion of the raceway upon which the lacing-hooks are located. Fig. 8is a section, partly in elevation, taken on line 8 8 of Fig. 5 lookingtoward the right in said figure. Fig. 9 is a section, partly inelevation,taken on line 9 9 of Fig. 5 looking toward the right in saidfigure.- Fig. 10 is an underneath plan View of the rotary picker. Fig.11 is a front elevation of said rotary picker.

Like characters refer to like parts throughout the several views of thedrawings.

In the drawings, 12 is a bracket adapted to be fastened to the frame ofthe machine. 13 is a hopper rigidly fastened to said bracket 12 andconsisting of a hollow casing 14, having a cylindrical bore and a bottom15. The hopper 13 is fastened. totlresbracket 12, so that the bottomthereof standsat an angle. A slraft 16 is'journaled to rotate in abearing 17, forming a portion of said hopper, and pro jectstherethrough, a pulley 18 beingfa'stened to the lower end of said shaftand the picker 19, fast to the upper end of said shaft.

The picker 19 consists of a hub 20, with arms 21 21 extending radiallyoutward therefrom and connected together at their outer ends by a rim22. The rim 22 has three blades 23 23 fast thereto, said blades beingformed concentric with the picker 19 or with the median axial linethereof, the front edge 24 of each of said blades being formed upon ahelical curve. The lower edge 25 of each of the blades 23 projects intoan annular groove 26, Fig. 4, which extends partly aroundithe bottom ofthe hopper 13. The lower edge 25 of each of the blades 23 projects intothe groove 26 as the picker is being rotated. A portion, however, of thebottom of said hopper is cut away to form a depression 27.

f lhe raceway 28 isjformed in two parts-a lowerportion29 and an u perportion 30. The lower portion 29 exten s for a part of its lengththatis, from a to b, Fig. 4-on a curve concentric with the interior of thehopas they are rotated in the operation of the machine. The lowerportion 29 of said raceway extends from the curved. portion a b thereofand from the point a, outwardly through a hole 31, provided in theperiphery of the hopper at the bottom thereof. The upper edge oftlreraceway extends downwardly from the point a. of said raceway as theraceway passes through the oper ing 31, beneath the plane in which theupper edge of the curved portion a b of said raceway is located.

The upper portion 30 ofthe raceway '28 is preferably located at one sideof said raceway, as illustrated in Fig. 8, so that said upper portionbears against the shanks of the lacing-hooks 32, located upon the lowerportion '29. Said upper portion 30 of the raceway terminates in a curve33 at its uppermost end, which extends upwardly in order to prevent anyclogging of the lacing-hooks.

The operation of the device is as follows: The lacing-hooks are placedin a mass in the interior of the hopper 13 and the picker 19 rotated bymeans of the pulley 1S and shaft 16. As the ditl'erent blades 23 of thepicker pass through the mass of lacing-hooks at the ower end of thehopper some of these lacinghooks are separated from the mass and arecarried by the picker-blades upwardly away from the mass oflacing-hooks, said lacing hooks resting on the front edge of thepickerblade with the heads located in the space between the picker-bladeand the interior of the hopper-casing 14, the shanks projecting towardthe center of said hop er. As soon as each picker-blade arrives a ovethe curved portion a b of the raceway the lacing-hooks slide off thepicker-blade andonto the raceway. Said raceway being at an angle, theselacing-hooks slide down the raceway on the lower portion 29 thereof, outthrough the opening 31, and downwardly along the raceway to the point inthe machine to which it is desired that they shall be uided. j

In Fig. 5 the picker-blade is illustrated with the point thereof at theend a of the curved portion a b of said raceway, with the raceway fullof lacing-hooks, and as the icker-blade is rotated it will be seen thatthe acing-hooks upon the picker-blade cannot slide therefrom onto theractnvay,,but will be carried past the raceway at the downwardlycurvedportion of its upper edge and will then slide off the; picker-blade intothe hop er. The lbwermost lacing-hook upon the pic-iterblade will betipped, as illustrated in Fig. 6 at 32, and carried back into the hop)er by the oint of the picker-blade, which wii owerinost lacing-hookacross the, lacing-hook 32 adjacent thereto and finally drop thesameinto the hopper in the recessed portion 27 thereof. As t iecurved'portion from uto b of the raceway part 29 is in ahneinent withthe picker-blade as it passes thereover, it will be seen thatsaidpicker-blade forms, in ell'cct,

l drag this a continuation of the raceway, so that the 'moment thepicker-blade arrives at the point b the lacing-hooks on the picker-bladecan begin to slide ofi' onto the curved portion of the raceway, downsaid raceway, and out of the hopper. Therefore on account of thisconstruction the picker can be continuously rotated instead ofintermittently rotated. as

r in devices heretofore constructed, and, moreover, when the raceway istilled, as illustrate in Figs. 6 and 7, the continuous rotation of thepicker-blade does not injure the books on the raceway, neither is thecontinuous rotation of said pickenblades blocked or interfered with bythe lacing-hooks which stand upon the raceway, the same being pushed outotthc way, as illustrated in Fig. (5, leav ing the raceway full andallowing the blade to pass over the uppermost lacing-hook 32 located.thereon Having thus described my invention, what I claim. and desire byLetters Patent to cure, is
